EHMS: Electronic Health Management System
A secure, cloud-based platform for managing patient records, appointments, and clinical workflows across hospitals and clinics. This project was tested by multiple small clinics including Bells University Clinic.
Duration
October 2021 - August 2022
Technologies
React, Node.js, PostgreSQL, Express, AWS, HL7 FHIR
Project Overview
EHMS is a comprehensive health information system designed to digitize patient care in resource-constrained environments. The platform supports patient registration, electronic medical records (EMR), appointment scheduling, lab integration, and telemedicine. I led the development of secure APIs and real-time dashboards to improve clinical decision-making.
Challenges and Solutions
Data Privacy & Compliance
Ensuring full compliance with local health data laws and preventing unauthorized access to sensitive records.
Offline Functionality
Clinics in rural areas needed to operate during network outages without data loss.
Legacy System Integration
Migrating paper-based and outdated digital records into a unified EMR system.
End-to-End Encryption & Audit Logs
Implemented AES-256 encryption and immutable audit trails for all user actions.
PWA with Local Sync
Built a Progressive Web App with IndexedDB for offline data entry and background sync.
Automated Data Migration Pipeline
Developed ETL scripts with validation rules to import and clean legacy records.
Key Features
Secure Patient Portal
Patients can access medical history, book appointments, and receive lab results securely.
Real-Time Clinical Dashboard
Doctors view active patients, pending labs, and critical alerts in real time.
HL7 FHIR Integration
Seamless interoperability with diagnostic labs and pharmacy systems.
Role-Based Access Control
Granular permissions for doctors, nurses, admins, and lab technicians.
Telemedicine Module
Video consultations with encrypted sessions and e-prescriptions.
